[A4] drifting gas mileage display

[docwyte at comcast.net]

Really hard to keep a truly constant throttle and be on a truly flat road. I wouldn't put any bearing on what you saw at all.

I purposely was looking at instantaneous but on a very flat road and even 
throttle. In my friend's A4 the display was quite steady but on this one, 
it would creep up and then creep down. Not a FB user.
